TECHNICAL FIELD

[0001] The utility model relates to a safety belt technical field, concretely relates to a safety belt. BACKGROUND

[0002] At present, the effective length of single safety rope of five-point safety belt used by high-altitude operation personnel is not more than 2m, the effective length of two safety ropes is not more than 1.2m, and the operation space range is limited; especially when the support is erected, the safety belt is frequently unloaded and hung, which influences operation efficiency, and some high-altitude operation personnel directly do not hang the safety belt due to fear of trouble; at the same time, after the safety belt hook is unloaded, it can only be wound together with the safety rope at the waist or held by hand, which influences the operation of workers and also easily causes the safety rope or hook to scratch the structure or building materials during the movement of operation personnel, resulting in falling or falling. Based on this situation, a novel safety belt is designed. CONTENT OF UTILITY MODEL

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1 andFigure 2 As shown, a seat belt includes an inner shell 1, a locking ratchet 2, and a locking clip 3;

[0026] The locking ratchet 2 is installed inside the inner shell 1, and the side wall of the locking ratchet 2 forms a groove space for winding the steel wire rope; the locking clip 3 is movably engaged with the locking ratchet 2;

[0027] The locking ratchet 2 is configured as a double ratchet structure, and the surface of the locking clip 3 is provided with a limiting block 33, which is in active contact with the locking ratchet 2.

[0028] A central rod 21 is provided at the axis of the locking ratchet 2. The central rod 21 is fixedly connected to the inner shell 1. The locking ratchet 2 is rotatably connected to the central rod 21 through a connector 22. A worm gear spring 23 is installed on the side wall of the central rod 21. The worm gear spring 23 is engaged with the inner wall of the locking ratchet 2.

[0029] The central rod 21 is used to support the locking ratchet 2 and provides the axis for the rotation of the worm gear spring 23. It is also equipped with a double ratchet structure to cooperate with the locking clip 3, which can stably engage in both directions, so as to stably clamp the wire rope when pulling down quickly.

[0030] The locking clip 3 includes an arc-shaped clip 31 and a connecting rod 32. Two arc-shaped clips 31 are provided, and the connecting rod 32 is fixedly connected to the two arc-shaped clips 31. A limit block 33 is provided on the arc-shaped inner wall of the arc-shaped clip 31. One end of the arc-shaped clip 31 that engages with the locking ratchet 2 is provided with a turning angle 34, which is biased towards the direction of rotation of the locking ratchet 2 during the release of the wire rope.

[0031] The arc-shaped clip 31 is configured such that one end of the angle 34 can be inserted into the locking ratchet 2, and the other end intermittently contacts the locking ratchet 2 under the action of the limiting block 33.

[0032] The locking clip 3 is equipped with an elastic element 35 for resetting; the ratchet teeth on the surface of the locking ratchet 2 are biased towards the direction of rotation during the release of the wire rope.

[0033] The elastic element 35 is used to provide the locking clip 3 with a rebound force, thereby ensuring that the wire rope can rebound by relying on the elastic element 35 when it is slowly released.

[0034] The outer wall of the inner shell 1 is covered by an outer shell, and a lifting ring is provided at one end of the outer shell. A hook for connecting to a wire rope is provided on the opposite side of the lifting ring.

[0035] The working process is as follows: when the wire rope is slowly released, the locking ratchet 2 rotates, driving the worm gear spring 23 to rotate; at this time, the two ends of the locking clip 3 are under the action of the elastic element 35. Due to the slow release, the elastic element 35 has enough time to retract the locking clip 3. However, when a special situation occurs, the wire rope is pulled quickly. At this time, due to the excessive rotation speed, after the corner 34 comes into contact with the locking ratchet 2, the elastic element 35 cannot pull the locking clip 3 back in a short time. As a result, the corner 34 and the locking ratchet 2 are locked, thereby locking the locking ratchet 2 and stopping the release of the wire rope, thus achieving fall prevention.
